Mangosteen Xanthones Tips and Some Laboratory Studies


I am looking for mangosteen tea preparation steps. Tips on how to steep/boil fresh skin or dry rind. The specific temperature for how many minutes or hours. However, I found out that xanthones, the dominant and most important mangosteen antioxidant, is relatively heat stable. Maybe boiling it is fine or steeping might be better.

Here are the other tips I found around the web. Most of them are supported by scientific studies.

1) Long term moderate consumption is recommended. Xanthones are absorb only in small amounts. Large doses are not beneficial and tend to lower absorption efficiency.

2) Aside from xanthones, it has other beneficial substance like catechins, polysaccharides, proanthocyanidins and sterols.

3) Oven drying 60ºC is recommended for maximum retention of sensory qualities.  Addition of whey powder is preferred over maltodextrin – it helps maintain xanthone content and improves its solubility.

4) Xanthones when taken with a high fat meal. Showed that xanthones in mangosteen juice are absorbed when ingested along with a high-fat meal, although release of xanthones from pericarp particles during digestion may be limited.

Some Health Benefits supported with laboratory studies…

1) Xanthones showed anti-leukemic activities in animal studies. The allanxanthone C and  macluraxanthone.

2) Twenty seven oxygenated xanthones showed anti-fungal activities against strains of Candida, Cryptococcus, Aspergillus.  The 1,2-dihydroxyxanthone was found to be the most effective.

3) Alpha-mangostin maybe useful in therapeutic treatment of breast cancer.

4) Laboratory study. Mangosteen xanthones showed high microbial activities.

5) Mangosteen xanthose  has an anti-angiogenic effect. Anti-angiogenic are substance used to control growth of new blood vessels.  Inhibitors are used to treat cancer, macular degeneration in the eye, and other diseases that involve a proliferation of blood vessels.

There are over 170 mangosteen related studies on Take some time seeing it for yourself.
